er with any suitable number of carbons and sheets of paper; further'toprovide a new and improved backing sheet to facilitate the handling of aplurality of sheets of Writing paper and carbon paper; further toprovide a new and improved means for mounting the carbon sheetwhen usedfor copying purposes; fur.

ther to provide a carbon paper holder of maximum simplicity, efliciency,economy and ease of operation; and such further objects, ad-

vantages, and capabilities as willlater more fully appear.

My invention further resides in the combination, construction andarrangement of parts illustrated in the accompanying drawings, and whileI have shown therein a preferred embodiment, I desire it to beunderstood that the same is susceptible of modification and changewithout departing from the spirit of my invention.

In the drawings:

Fig. 1 is a plan view of my improved backing sheet'and contents thereof,the top sheet of writing paper having been removed.

Fig. 2 is a vertical cross-sectional view on line 2-2 of Fig. 1, thesheets of writing paper having been removed.

Fig. 3 is a fragmentary view of the carbon paper holder with a portionof the top or front strip broken away.

Fig. 4 is a top edge view showing the means of assembling the backingsheet,- top or front strip, and the carbon paper. 7

Fig. 5 is a plan view of an'eyelet or tip adapted for use with theflexible tape for assembling the holder.

Fig. 6 is a plan view of the eyelet or tip as applied to the end of theflexible tape.

Referring to the drawings, my new and improved carbon paper holder isgenerally designated at 1, and comprises a backing sheet 2, a series ofsheets of carbon paper 3, and a front or top strip 4. The backing sheetis preferably of heavier composition than the ordinary paper and mayconsist of oiled paper or of other suitable and desirable material, andis generally of the same length as the carbon sheet. Any number ofsheets of carbon paper may be inserted, depending upon the number ofcopies that are desired.

A series of spaced openings 5 are provided through the upper strip 4,carbons 3, and

backing sheet 2. The configuration of these openings is more clearlydisclosed in Fig. 3

-of the drawings, the central portions of the perforations being ofcircular form, the pur' pose of which is to enable the operator to seethat the top sheet and underlying sheets and backing are in their properrelation and position.

The upper strip, carbon sheets, and backing sheet are held together bymeans of a flexible tape 6 of a length substantially the same as thewidth of the backing'sheet and -upper strip. An eyelet or tip 7 issecured to the end of the tape 6 by means of a pair of overhangingportions or flanges 8 and 9. As more clearly disclosed in Figs. 5 and 6of the drawings, these flanges are adapted to be bent over the tapethereby tightly clamping and holding the tapein position. When the tapehas been passed through the perforations 5, the tip 7 is tucked underthe u perstrip 4 as clearly disclosed in Fig. 4 o the drawings.

J The letter paper 10 is inserted between the sheets of carbon paper,the letter aper stopping when the upper end thereof abuts the tape. Anynumber of sheets of writing paper may be inserted, depending upon thenumber of sheets of carbon paper that are detachably held .in the copyholder. The stenographer can arrange the desired number of carbon papersin this device in the morning, and will not have to change the same 3throughout the day for any letters requiring the same number of carbons,but all she will have to do will be to insert the pages or sheets ofwriting paper in their proper laces between and over the carbon sheetswit out havnumber of carbon sheets.

ing to pick up and handle the separate sheets of carbon paper. Thus thedevice holds the. carbon paper in assembled form for its use. If agreater or less number ofsheets are desired, this can be effected byremoving the tape and adding to or' detracting from the The constructionreadil facilitates the change of the number of car on sheets and theremoval of the sheets of writing paper so that the 0 enter may removeall-of the sheets of writmg paper at one time without the necessity ofretracting each of the sheets of paper separately. A

' small'portion is cut ofi of theecor'ner of each of the sheets ofcarbon paper so that all that; willbe necessary for the retraction ofall of thesheets oi paper will be that the operator the messy conditionthat usually results 'when it is necessary to handle a number of sheets.of carbon paper.

The composite construction of the holder facilitates the introduction ofthe same into the machine with any suitable number of carbons and sheetsof paper. The separate elements ofthe holder are easily and quicklyremoved for the insertion of a greater number of carbons or for theremoval of some of the' carbon sheets. ,By making the upper strip 4separately from the backing sheet, it is not necessary to have somepaper fastening means which 1n time would break oil. The flexible tapeand the particular spacing of the perforations provides for a perfectalinement of not only the backing member, upper strip and sheets ofcarbon paper, but the tape also provides an abutment for the alinementof the sheets of writing paper.

It will thus be seen that my invention has the advantages of cheapnessand simplicity, the ease with which the backing sheet and contents canbeinserted in the machine and the fact that it holds thewriting sheets andcarbon sheets in perfect register. The construction allows for the readyinsertion of the holder in the typewriting machine and eliminates thedifficulty experienced in inserting a plurality of sheets of writingpaper and carbon pa er simultaneously in a machine and keeping them inregister or alinement. Having now disclosed my invention,

- I claim:-

1.- A carbon sheet holder comprising a sheet for backing a plurality ofsuperposed carbon sheets, a transversely disposed top engagement withthe top strip, the backing typewriting machine.

3. A carbon sheet holder comprising a sheet for backing a plurality ofcarbon sheets, a separate top strip extending transversely across thesuperposed carbon sheets and backing sheets near one end thereof, andflexible interlacing means for detachably holding said top strip, saidcarbon sheets and said backing sheets in assembled relation, saidinterlacing means constituting an abutment to be engaged by sheets'ofwriting paper inserted between said carbon sheets, so that they may allbe placed in atypewritting machine as a single unit. q

4. A carbon 1 sheet holder comprising a sheet for backin a plurality ofsuperposed carbon sheets, a at flexible member providing an interlacingmeans for holding said backing member and said carbon sheets in properalignment, said flat flexible member constituting an abutment to beengaged by sheets-of writing paper so as to facilitate the alignment ofsaid sheets of paper while being placed in position.

Inwitness whereof, I hereunto subscribe my name to this specification.
